iOS Scanner Does Not Capture Barcodes

[diloreto]

I have tried implementing this plugin several times, executing by building a phoneGap project, opening in Xcode, then building and pushing to my iPhone 6s+ (latest iOS). I can get the scanner to show up with a green box and red line through it, and then when I hover over barcodes, the debugger in Xcode shows data apparently, but the scanner does not stop reading/capture. I never get to the "success" function and must cancel it to get out.

• Has anyone else experienced this? What did you do?
• Is this unique to IPhone 6s+ ?
• Is there better documentation for this plugin anywhere? This one is lacking; you cannot have an "options" parameter for a function and not specify exactly what can be passed?

Here is my code:

function scanItem(){

        var camOpt = {
              "preferFrontCamera" : false, // iOS and Android
              "showFlipCameraButton" : false, // iOS and Android
              "formats" : "", // I WANT TO SUPPORT ALL BARCODE FORMATS
              "prompt" : "Place a barcode inside the scan area", // supported on Android only
              "orientation" : "portrait" // Android only (portrait|landscape), default unset so it rotates with the device
          };

          cordova.plugins.barcodeScanner.scan(
          function (result) {
                          // Never enters on compiled app
              alert("We got a barcode\n" +
                    "Result: " + result.text + "\n" +
                    "Format: " + result.format + "\n" +
                    "Cancelled: " + result.cancelled);
          }, 
          function (error) {
              alert("Scanning failed: " + error);
          },
          camOpt
       );
}

I think you have to remove the "formats" : "" or use null instead of ""

Thank you - I'll give that a whirl. That still doesn't answer why when I
hover over barcodes with the barcode scanner open that it does not "pick
them up". Scanner continues to try.

it works fine on my iphone5s
here is my code:

cordova.plugins.barcodeScanner.scan(
            function (result) {
                alert("We got a barcode\n" +
                    "Result: " + result.text + "\n" +
                    "Format: " + result.format + "\n" +
                    "Cancelled: " + result.cancelled);
                window.location.href="index.html#goods/goodsview?code="+result.text;
            },
            function (error) {
                alert("Scanning failed: " + error);
            },
            {
                "preferFrontCamera" : true, // iOS and Android
                "showFlipCameraButton" : true, // iOS and Android
                "prompt" : "Place a barcode inside the scan area", // supported on Android only
                "formats" : "QR_CODE,PDF_417,EAN_8,EAN_13", // default: all but PDF_417 and RSS_EXPANDED
                "orientation" : "landscape" // Android only (portrait|landscape), default unset so it rotates with the device
            }
        );

Thanks - and how are you envoking that? I'm doing a $$(element).on('click',
scanItem); which calls that. The scanner will pop up, but not pull the item
code. Have you seen this before?

User Error - I had to do a "Xcode Clean...Build" and it worked. Must have been stale compiled files.

[sokulski]

I believe I am experiencing the same issue. I build using the Cordova CLI, I am starting the barcode scanner via a button, and I can see the camera with the overlay.

When looking from XCode I can see various "bits" items showing up in the console as I point my camera at a barcode. But the scan is not completing and firing either the success or failure functions.

I tried running Clean on the project in Xcode as well as Clean Build Folder with no relief.

Any idea what I should try next?

[diloreto]

It's hard to say - I put this in as the new options parameter:

var camOpt = {
"preferFrontCamera" : false, // iOS and Android
"showFlipCameraButton" : false, // iOS and Android
"prompt" : "Place a barcode inside the scan area", // supported on Android
only
// "formats" : "EAN_8,EAN_13,QR_CODE", // Specify formats
"orientation" : "portrait" // Android only (portrait|landscape), default
unset so it rotates with the device
};

Recompiled from cordova, then cleaned the project in XCode, rebuilt and
pushed to IPhone and now works. Regardless the library probably could stand
a bit of an overhaul, as the only other library I found for barcode
scanning wanted some insane amount of money ($1k/yr +).

Try that.

I was able to resolve this. I think it may have been a misconfiguration on my end. Either that or cleaning the project worked.

At any rate, don't keep this issue open on my account. Thanks!
